Good day. I've been having some problems with URIDNSBL plugin for Spam Assassin. One of blocked mail came from emailframer.com . After investigating issue this came up:
host -t ns emailframer.com emailframer.com name server ns1.barak.net.il. emailframer.com name server ns.barak.net.il. host -t a ns.barak.net.il ns.barak.net.il has address 212.150.48.169 And this brough me to: http://www.spamhaus.org/SBL/sbl.lasso?query=SBL22121 The problem is - barak.net.il is one of the MAJOR Israel's ISPs, and since MANY hosts have NS record matching it, this SBL record block ALL sites hosted on it. To solve this problem (temporary ofcourse) i've disabled NS lookups in the plugin. What I wanted to know - is this an expected behaviour? If so - how to handle this situation? Best regards, Eli Yukelzon
